In the following, guiding attention into Fig. 2,3 and 4, it illustrates the depositions for the forming member for including end effector 20
First 40 details.Deposition head 40 includes: the elongated clip band bucket 66 with feed end 70；With material deposit apex 72, from the material
Expect that deposit apex 72 squeezes out the pearl material 44 (Fig. 1) that simultaneously deposit fiber strengthens polymer, as previously described.Carrying bucket 66 secretly includes internal capillary
Pipe 68, the capillary 68 have the first upstream end 68a and second downstream 68b opposite with upstream end 68a.Capillary 68 is from folder
Material deposit apex 72 with bucket 66, which rises, extends longitudinally to assembling area 86, wherein fibrous reinforcement 76 is introduced into and with being introduced into
To the polymer 80 of the entrainment bucket 66 of the upstream of assembling area 86 flowing stream and converge.
When fibrous reinforcement 76 is introduced into the flowing stream of polymer 80, between fibrous reinforcement 76 and polymer 80
Fibrous reinforcement 76 is dragged in the upstream end 68a of capillary 68 and is subsequently passed through the capillary 68 by viscous interaction.Work as entrance
When assembling area 86, fibrous reinforcement 76 is entrained in the flowing stream of polymer 80, and is carried through hair in company with polymer 80
Tubule 68 is until carry the material deposit apex 72 of bucket 66 secretly, wherein polymer 80 and the fibrous reinforcement 76 of entrainment are squeezed out jointly
For pearl material 44.
The downstream 68b of capillary 68 can couple with extrusion die 42, wish the poly- of cross sectional shape to squeeze out to have
Close object pearl material 44.In some applications, extrusion die 42 may not be required.Capillary 68 has depending on many factors
Internal diameter " D ", many factors include particular deposition application, and the print resolution and fiber of the component 26 (Fig. 1) manufactured are strong
The hope plot ratio of compound 76.Plot ratio comprising fibrous reinforcement 76 in the polymer be capillary 68 internal diameter " D " with
Form the quantity of the fiber of fibrous reinforcement 76 and the function of both diameters.The length of capillary 68 can also influence the poly- of entrainment
The amount for closing object and fiber interaction, needs it that fibrous reinforcement 76 is moved through capillary 68.
The feed end 70 of entrainment bucket 66 is provided with the guide wire 74 being centered about, can will be fine by the guide wire 74
Fortifier 76 is tieed up longitudinally to feed from fiber supply and feed part 48 (Fig. 1).The downstream 74a of guide wire 74 is tapered, and is wrapped
It includes and the coaxillay aligned central opening 82 (Fig. 3 and 4) of capillary 68.After being fed in guide wire 74, fibrous reinforcement
76 are directed across opening 82 with 68 axis of capillary with being aligned, and enter the assembling area 86 for converging it, are exposed and are melted
Polymer wetting, the outside that melt polymer flows through guide wire 74 enters capillary 68.It is converged as fibrous reinforcement 76 enters
Area 86 is entrained in the polymer 80 for flowing through the entrance of assembling area 86 capillary 68.
The feed end 70 of entrainment bucket 66 further includes surrounding the cyclic polymer channel 69 of guide wire 74.Implement at one
In mode, flowable melt polymer 80 can be along usually parallel with the direction that fibrous reinforcement 76 is fed in guide wire 74
Direction, via the polymer inlet 69a (as shown) at feed end 70, and be introduced into cyclic polymer channel 69.
Alternatively, in another embodiment (not shown), flowable melt polymer 80 can be presented along with by fibrous reinforcement 76
It is sent to the direction of the direction transverse direction in guide wire 74, and channel 69 is entered by carrying the avris of bucket 66 secretly by crossfeed.
Polymer 80 is with pressure " P1" be injected into polymer inlet 69a from polymer supply department 50, and flow into and pass through
Annular channel 69.Annular channel 69 is tapered, and is converged using the end 74a that is tapered of guidance part 74, and the polymer 80 of flowing is flowed
Fibrous reinforcement 76 is crossed and crosses, into the upstream end 68a of capillary 68.Pressure " P1" it is greater than the material deposit apex of entrainment bucket 66
Atmospheric pressure " P at 72a", thus, there are pressure difference P between opposite end 68a, 68b of capillary 681-Pa.The pressure
Difference helps to draw fibrous reinforcement 76 and be entrained in the polymer 80 of flowing.

Enter to carry secretly bucket 66.Electric heating coil 52a provides required heat, to keep polymer 80 to be in the flowable shape for wishing viscosity
State.It is desirable that pressing the temperature bigger than the temperature at material deposit apex 72, temperature of the retaining clip band bucket 66 at feed end 70
Degree, to guarantee to soak fibrous reinforcement 76 enough, just as being initially drawn into capillary 68 it.In order to polymerization
Object is advanced along the length of entrainment bucket 66 to change the heat for being supplied to polymer 80, and thus controls the viscosity of polymer 80, is added
Heat coil 52a can have bigger than the coil turn at material deposit apex 72 at the feed end 70 on entrainment bucket 66
The coil turn of quantity.
When in use, one or more fibrous reinforcements 76 can be loosely fed in guide wire 74, so that it
Do not placed by the compression of any general amount, that is, they are not pushed in guide wire 74, to avoid fibrous reinforcement 76
Buckling.As previously mentioned, entrainment bucket 66, which is heated to, keeps the flowable temperature of polymer 80, and guarantee that substantially complete wetting is fine
Tie up fortifier 76.Pressure P1Under polymer 80 be introduced in polymer inlet 69a, filling annular channel 69, and establish poly-
Close the flowing that object 80 enters the upstream end 68a of capillary 68 via assembling area 86.In polymer inlet 69a and material deposit apex 72
Between the polyalcohol pressure difference P that establishes1-PaPolymer 80 is kept to flow to capillary 68.In other words, polymer 80 by from
Relatively high pressure P1Under polymer inlet 69a flow to relative lower pressure PaUnder material deposit apex 72 seek to put down
Weighing apparatus.
According to pressure difference P1-PaThe polymer 80 of generation passes through the flowing of assembling area 86, leads to polymer 80 " catching " and draws
The fibrous reinforcement 76 that the upstream end 68a of capillary 68 is flowed into together with polymer 80 is taken, there, fibrous reinforcement 76 is entrained
Into polymer 80.In addition, according to capillary caused by the molecular separating force between polymer 80 and surrounding capillary 68 is passed through
Effect, fibrous reinforcement 76 are drawn through capillary 68.As fibrous reinforcement 76 is drawn into capillary 68, fiber is strong
Compound 76 is entrained in the polymer 80 of flowing and is extruded, and is then deposited in the pearl material 44 of thawing in company with polymer 80
(Fig. 1), to be rasterized on substrate 23 and the pantostrat 22 of forming member 26 with end effector 20.
When foring the layer 22 or other feature of component 26, cutter 46 cuts off pearl material 44, and polymer supply department
50 are blocked, until end effector 20 is ready to deposit next layer 2.Cutting pearl material 44 causes to cut off polymer 80 and folder
Take both fibrous reinforcements 76 in polymer 80 to.In some applications, feeding fibrous reinforcement 76 can be temporarily interrupted, with
Just it is deposited as the pearl material 44 (lacking fibrous reinforcement) of straight polymer 80, to form the layer 22 for not including fortifier.
In the following, guiding attention to Fig. 5, the deposition of the end effector 20 using the above-mentioned type is broadly illustrated
